A Russian-born Jew, Guzik served as chief accountant and treasurer for the outfit. He earned his nickname—“Greasy Thumb”—because he smoothly peeled bills from a wad of cash when administering bribes, commissions, and other payoffs. When a hoodlum named Joe Howard slapped the roly-poly Guzik around, it was Capone who came to his friend’s defense. Guzik remained fiercely loyal to Capone ever after.
